  1. Hello. I would like some help troubleshooting some printing issues I have recently been having. My hospital got a 3D printer several months ago and we have been successful with our prints and making complex models with tough PLA and PVA support (I also attached a previous successful model printed with same settings). Recently, my models are not adhering to the print bed to itself. I have tried with PLA supports and PVA supports. I have unloaded and reloaded the filaments as well. I also reset the print settings to default. I have tried all different recommended settings with no help. My printer continues to print strings that are not adhering to anything. Sometimes it starts to adhere to bed and then fails or will not adhere to plate at all. The only causes I can think of are the following: Filament hydration? I am in New Mexico, an arid climate but do not store the filaments in a desiccator. Perhaps this is the issue? Settings not correct? Print speed too fast? We recently tried ninjaflex 3.0 mm and did not have any success with this. We attributed this to the size of 3.0mm. Print head clogged? The print heads seem to be extruding fine... Should I be doing regular cleaning?
